Image Resizer

How this resizer works

Choose an image, then enter the width and/or height you want. With aspect ratio locked, typing a new width automatically recalculates the height (and vice versa) so proportions stay correct. Uncheck the lock if you deliberately want to stretch or crop the image to an exact size.

Choosing dimensions

Common targets include exact pixel sizes required by a website, marketplace listing, or social media profile. Since resizing up beyond the original resolution stretches existing pixels rather than adding real detail, the sharpest results come from resizing down or close to the original size.

Privacy by design

Like the rest of these tools, resizing happens locally using your browser's canvas rendering — nothing is uploaded, and it keeps working even without an internet connection once the page has loaded.
